Improvement in spinning-frame



fluird (glatte 'aient IMPROVEMENT IN SPINNING-FRAME.

m The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern Be it known that I, SAMUEL B. PARMENTER, of Iiewiston, in the county of Androscoggin, and State of Maine, have invented anew and improved Lifting-v Rod for Spinning-Machlne.; and I do hereby declare that the following is a full and exact description of the same, reference being had 4to the accompanying drawings, 'and to the letters of reference marked thereon.

This invention relates to an improvement in ringrail lifting-rods for ring-spinning and twisting; and consists inA providing the lifting-rod, upon which the ring-rail rests, with an adjustable top.

' The details of construction will be fully described hereinafter.

In the drawings- Figure l is a side elevation of my invention.

Figure 2 is a longitudinal vertical section of the head Y C and bar D.

Figure 3, a transverse vertical section of the same arrangement; and

' Figure 4 isa perspective view of the head C and slidingbar D.

To enable others skilled in the art to which my invention appertains, to make andV use the same, I will 4 proceed to describe fully its construction and operation.

In the ring-spinning and twisting machines in general, use, the top ofthe lifting-rod is made in one solid' piece, rigidly attached to the rod.

. This construction, in practice, occasions great diculty whenever the rings are not concentric with the spindles, becauseadjustment is impossible. At such times the traveller is caused to bear irregularly upon the ring, and the latter thus wears unequally, andv gives the `traveller a vibrating mot-ion.

.'lo make good yarn, it is essential that the rings should be concentric with the spindles.

The object of this invention is to enable the ringrail to be readilyadjusted, Whenever it may be necessary for the purpose specified.

A represents the ame, in which move the liftingvrodsB. v

C represents theA top or head-of the rod, which is provided with the sides c c, -which form a groove for the sliding bar D, having the piu d.

The two parts G D are conne ated by screws, which prevent displacement.

Inorder that lateral movement may be permitted, the top O is slotted, as shown.

E represents the rail, which holds the rings.v

This rail rests upon the top C, as shown, its notches e fitting over the latter in such manner that longitudinal movement is ,rendered impossible.

The pins d extend through the rail, as shown.

The bar D lits snugly within the rails, its ends resting against the sides ofthe latter.

From this description, it will be perceived that the rail may be adjusted laterally within certain limits in either' direction by simply moving the bar D, which operation may be accomplished through the medium of the rail.

When the proper adjustment is made, the screws connecting the parts 0 D may be tightened to secure the rail in place.

By the construction herein described,.an entire rail holding sixty rings, more or less, may be adjusted whenever it may be necessary.

The operation is exceedingly' simple and eiective.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

rlhe combination of the head O and the adjustable bar D, when constructed as described, with the lifting- 'rods B and ring-rails E, substantially as described, for

the purpose se't forth. y

This specification signed and witnessed, this 2d day of March, 1869.
